Acts 26:24-27

And as he thus spake for himself, Festus said with a loud voice, Paul, thou art beside thyself; much learning doth make thee mad. But he said, I am not mad, most noble Festus; but speak forth the words of truth and soberness. For the king knoweth of these things, before whom also I speak freely: for I am persuaded that none of these things are hidden from him; for this thing was not done in a corner. King Agrippa, believest thou the prophets? I know that thou believest.
